BACKGROUND Technical Field

The present invention is related to a transmitting scheme in a radiocommunication system, and more particular to a downlink schedulingmethod and device for supporting a narrow band transmission.

Related Art

In the #69th 3GPP (3rd Generation Partner Project) RAN (Radio AccessNetwork) plenary, NB-IOT (NarrowBand Internet of Things) wasestablished. The NB-IOT supports three different operation modes(RP-151621).

1. Stand-alone operation: deployed on a spectrum used by GERAN system.

2. Protection zone operation: deployed on a non-use resource block ofthe protection zone of LTE (Long Term Evolution) carrier.

3. In-band operation: deployed on a resource block of the LTE carrier.

Further, in the NB-IOT, a UE (User Equipment) supports a radio frequencybandwidth of 180 kHz (kiloHertz) in uplink and downlink, i.e. one PRB(Physical Resource Block).

In the #83 3GPP RAN plenary, the NB-IOT system introduces the conceptsof single-tone transmission and multi-tone transmission in the uplink.The single-tone means that when the UE is sent in the uplink, it mayonly be transmitted on one sub carrier. The multi-tone transmissioncontinues using a transmission manner of uplink SC-FDMA (SingleCarrier-Frequency Division Multiple Access), i.e. it is transmitted onthe PRB (Physical Resource Block) consisted of a plurality of subcarriers. One advantage of the single-tone is that the implementation ofUE uplink radio frequency is simple, it does not have a problem of PAPR(Peak to Average Power Ratio), the implementation cost is low, and thelower power consumption may be maintained, so as to improve the usingtime of the terminal battery.

For the traditional LTE system, a downlink HARQ-ACK is transmitted onPHICH (Physical UplinkHybrid ARQ Indicator Channel) or PDCCH (Physicaldownlink Control Channel). For NB-IOT, an intuitive idea is to decreasethe types of the physical layer channel as much as possible, so as toreduce the complexity of the UE. Therefore, a possible scheme is thatthe HARQ-ACK is transmitted on the physical layer data channel, i.e.physical channel would not be particularly dedicated for the HARQ-ACK.Based on the above scheme, a problem needed to be solved is that how toachieve the co-existence of the data transmitted on the physical layerdata channel and the HARQ-ACK, i.e. avoiding the collision of both.

SUMMARY

The inventor researches and discovers that if a downlink HARQ-ACK and adownlink data are transmitted on the same physical layer channel, it isa problem require to be solved that how to configure a time frequencyresource occupied by the downlink HARQ-ACK and a time frequency resourceoccupied by the downlink data to a UE. An intuitive scheme is that thebase station transmits two independent downlink signaling to indicatethe time frequency resource occupied by the downlink HARQ-ACK and thetime frequency resource occupied by the downlink data respectively. Theabove intuitive scheme may result in excessive signaling redundancy orwaste of resources. For example, the downlink HARQ-ACK may only existsin a part of PRBs occupied by the downlink data, i.e. the time frequencyresource occupied by the downlink data in each PRB is variable.Therefore, the scheduling signaling for the uplink data may need toallocate resource for each PRB.

The present invention provides a solution for the above problem. Itshould be noted that in the absence of conflict, the embodiments and thefeatures of the embodiments of the UE (User Equipment) of the presentinvention may be applied to a base station and vice versa. Further, inthe absence of conflict, the embodiments and the features of theembodiments of the present invention may be combined with each otherarbitrarily.

The present invention discloses a method for supporting a narrow bandcommunication in a UE, which includes the following steps:

step A: receiving a first signaling; and

step B: receiving a wireless signal on a target time frequency resource.

Wherein the first signaling indicates a first time frequency resource,and the first time frequency resource includes a second time frequencyresource. The target time frequency resource includes a time frequencyresource of the first time frequency resource except the second timefrequency resource. The target time frequency resource and the secondtime frequency resource are orthogonal. The first time frequencyresource includes T1 sub frames in a time domain and includes P1 subcarriers in a frequency domain. The second time frequency resourceincludes T2 sub frames out of the T1 sub frames in a time domain. The T1and the P1 are a positive integer respectively, and the T2 is smallerthan the T1.

In one embodiment, the essence of the above method is that the UEtransmits the wireless signal on a part of time frequency resource ofthe first time frequency resource indicated by the first signaling. Inthe above method, the first signaling does not need to explicitlyindicate the target time frequency resource, so as to save the signalingoverhead.

In one embodiment, a transmission channel corresponding to the wirelesssignal is DL-SCH (Downlink Shared Channel).

In the above method, the UE avoids occupying the second time frequencyresource by default to transmit the wireless signal, i.e. does not needthe configuration of the first signaling, such that the overhead of thefirst signaling is further saved. However, when the second timefrequency resource is idle, the above method can not flexibly use thesecond time frequency resource. In an alternative scheme, the followingmethod solve this problem.

The present invention discloses a method for supporting a narrow bandcommunication in a UE, which includes the following steps:

Wherein the first signaling indicates a first time frequency resource,and the first time frequency resource includes a second time frequencyresource. The target time frequency resource includes a time frequencyresource of the first time frequency resource except the second timefrequency resource. The first signaling indicates whether the targettime frequency resource includes the second time frequency resource. Thefirst time frequency resource includes T1 sub frames in a time domain,and includes P1 sub carriers in a frequency domain. The second timefrequency resource includes T2 sub frames out of the T1 sub frames in atime domain. The T1 and the P1 are a positive integer respectively, andthe T2 is smaller than the T1.

In one embodiment, in the above method, the first signaling indicateswhether the target time frequency resource includes the second timefrequency resource, and determines whether the wireless signal mayoccupy the second time frequency resource according to the using stateof the second time frequency resource. Compared to not fully occupyingthe second time frequency resource, the above method improves theresource utilization efficiency, and the cost thereof is a slightincrease in the overhead brought by the first signaling.

In one embodiment, whether the target time frequency resource includesthe second time frequency resource is indicated by one bit of the firstsignaling.
